WILLIAM R. DAVIS, OF BOURBON, INDIANA.

SIQLL FoR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 416,578, dated December 3, 1889 Application filed August 13, 1889. Serial No. 320,627. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM R. DAVIS, a citizen of the United States of America, residing at Bourbon, in the county of Marshall and State of Indiana, have invented certain new and useful Improvements in Sills for Buildings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to sills for buildings; and it consists in the improved construction and combination of parts hereinafter described and set forth, whereby a cheaper and better sill is formed than ordinarily.

In the accompanying drawings, forming part of this specification, Figure 1 represents a sectional plan view of so 'much of a sill as is necessary to show my invention. Fig. 2 is .a perspective view of the corner-casting. Fig.

3 is a detail perspective view showing a cornerpost in position on the hollow tenon, part of the post being broken away.

In constructing a sill according to my invention I take planks A A, generally about two inches in thickness and joined together at their adjacent edges to form miter-joints a, so as to be at right angles to each other and form the inner and outer faces of the sill. An angle-casting B, of about the same width and thickness as the planks A A, em

braces the corner of the inner planks, so as to brace the connection of the latter, and also furnish the spacing means at such point against which the inner plank-sections A A can be positioned. Additional short planksections F are also positioned against the inner sections AA in the line of the respective portions of the casting B. The sections A A are also connected together by a miterjoint. The outer timber-sections are braced by means of a casting (see Fig. 2) consisting of the members B B, located at right angles to each other and provided on their upper side and at their intersecting point with a square projection 00, adapted to form a tenon to enter a recess in the lower end of the corner-beam. The projection w is preferably made hollow, so as to secure lightness of the structure. The members B B each consist of a vertical web provided at its upper and lower edges with horizontal flanges 1 which secure proper space between the planks. Ad-

ditional plank-sections F F are also interposed behind the outer sections A A in the line of the members B B.

It will be noticed that the several planksections employed are all of comparatively short length, thus enabling the sill to be cheaply made up of short pieces. These sections are rigidly connected together by means of the bolts 0, some of which pass entirely through the several thicknesses of material, While others only pass partially through. The arrangement described enables a sill to be made up of short pieces of plank instead of the thick lengths of beams heretofore used. Furthermore, the plank-sections are more suitable for this purpose, since they are always more or less better seasoned timber. The short sections are so secured together that they break joints, and th us avoid weak places that might be occasioned by using short lengths of plank.

I claim- 1. The combination of the inner and outer pairs of parallel plank-sections A A, arranged at right angles to each other, of intermediate short plank-sections arranged between and parallel with said sections A A, and an anglecasting for bracing the angular portions of said planks, all bolted together to form a single sill or wall, substantially as set forth.

' 2. The combination of the inner and outer pairs of parallel planks A A, arranged at right angles, as described, of intermediate fillingplanks arranged between and parallel with said sections and located to break joint, an inner angular casting B, and outer casting having members B B, all bolted together, substantially as set forth.

3. The combination of the inner and outer planks A A at right angles to each other, intermediate filling-planks arranged to break joint, and a casting having members B B and upper tenon projection, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM R. DAVIS.
